University College London (UCL) is a public research university in London, England, and the oldest and largest constituent college of the federal University of London. Founded in 1826 as London University, UCL was the first university institution established in London and the first in England to be entirely secular, to admit students regardless of their religion, and to admit women on equal terms with men. The philosopher Jeremy Bentham is commonly regarded as the spiritual father of UCL, as his radical ideas on education and society were the inspiration to its founders, although his direct involvement in its foundation was limited. UCL became one of the two founding colleges of the University of London in 1836. It has grown through mergers, including with the Institute of Neurology (in 1997), the Royal Free Hospital Medical School (in 1998), the Eastman Dental Institute (in 1999), the School of Slavonic and East European Studies (in 1999) and the School of Pharmacy (in 2012).

University College Hospital (UCH) is a teaching hospital located in London, United Kingdom. It is part of the University College London Hospitals NHS Foundation Trust and is closely associated with University College London (UCL).
